Application circuit
The recommended application circuit is shown in fi gure 3.
Figure 3. Recommended application circuit.
Board Layout – Decoupling Circuit and Ground Planes
It is important to take care of the layout of the application circuitry to achieve optimum performance of the transceiver.
A power supply decoupling circuit is recommended to fi lter out noise, to assure optimal product performance. It is
further recommended that a contiguous signal ground plane be provided in the circuit board directly under the trans-
ceiver to provide a low inductance ground for signal return current. It is also recommended that the shield posts be con-
nected to the chassis ground to provide optimum EMI, ESD and EMS performance. This recommendation is in keeping
with good high frequency board layout practices.
